Tickets issued by the tax authorities can be refunded if they are required to be refunded within the same day (before the service hall closes). At the same time, the tax paid in cash and tax receipts can also be invalidated, and the tax can be refunded (except those paid by credit card). If it exceeds the day, it can only be invalidated, and the tax paid cannot be refunded. It can only be handled according to the tax refund procedure, but the tax refund procedure is quite complicated, and it is possible that the time, energy and expenses required for tax refund exceed the tax paid. Therefore, when applying to the tax authorities for invoicing, the contents of each column of the application form need to be filled in correctly to prevent unnecessary losses.
